    摘要: Methods and apparatus for installing a pipe nipple in the wall of a submerged casing in a fluidtight manner. The casing is tapped by cutting a hole in its wall sufficient that the nipple can be slidably inserted therein. An explosive charge of predetermined magnitude is detonated in the nipple and opposite the casing wall so as to expand the nipple in the hole.
